Doing it this way means it's a lot easier to find things.  I know all the MAT files from everyone making stuff for the MFD will be in the MFD directory structure.  If I want to move the dress from, say, the V3 runtime to a dedicated DAZ clothing runtime, it's easy to find all the files and the add-on products that I've bought.

 

Unfortunately, even DAZ doesn't do this with all of its expansions :(
